Two infant orangutans that were confiscated from smugglers by Malaysian authorities in July were returned to Sumatra on Tuesday.
The orangutans will undergo a rehabilitation program to prepare them for eventual release into the wild.
The animals arrived at Kuala Namu International Airport in Deli Serdang, North Sumatra, Indonesia.
The orangutans had been stuffed into a suitcase in July and were discovered, reports the Malay Mail Online. They were saved from being sold as pets.
Four men were arrested for possessing the critically endangered primates.
